Titan IV

The Titan IV was a family of rockets (including the IVA and IVB) that launched satellite payloads for the U.S. Air Force (USAF). Launches were conducted from Cape Canaveral Air Force Station, Florida and Vandenberg Air Force Base, California.

The Titan IV was the last of the Titan family of rockets. It was retired in 2005 due to its high cost of operation. The final launch (B-30) from Cape Canaveral AFS occurred on 29 April 2005, and the final launch from Vandenberg AFB occurred on 19 October 2005. Lockheed Martin Space Systems built the Titan IVs near Denver, Colorado, under contract to the US government.

A Notable Payload of the Titan IV was the Cassini Huygens probe.
